I have taken off the catalytic converter and put a test pipe on my S2k recently. My issue is that because I took off the cat my car is now having a check engine light problem. I really love driving my car but I just hate that yellow check engine light looking at me Does anyone know how you all deal with the check engine light problem? Resenting the cel is only temporary!!! thanks

Search search search. You need spark plug anti-foulers.

What year is your car because I know 06+ is having trouble getting the CEL to go away no matter what they try.
